This may seem remote from neurology but it must be remembered that respiratory capacity depends not only upon lung field and thoracic mobility but also upon the muscle power and coordination of the respiratory muscles which include those of expiration as well as inspiration. Measurements of vital capacity using a spirometer can be recorded by means of a graph and give some idea of the power of the muscles and mobility of the thorax. Consecutive measurements at intervals give an idea of progress or rate of deterioration. A measurement of forced expiratory volume is one method of assessing the power of the expiratory muscles.
This group includes the abdominal muscles. Thus, a functional assessment by a physiotherapist must include specific tests, as appropriate to the patients, bearing all the areas indicates in mind. Such functions as the ability to move about in bed, transfer from bed…
